It would be nice if there is an OID to get volume of data used by Sim A and by Sim B for the current month.
You can set a Bandwidth Allowance but if you have a lot of devices it is hard to control which device is near the limit.
For this we want use PRTG a SNMP monitoring system, which can give warnings and alarms.
But we cannot find a OID for the Data usage form the Slots.
in the MIB we didn’t find them.
